Inaccessible boot device and Recovery system boot failed after resizing partition

Question: Inaccessible boot device and Recovery system boot failed after resizing partition

Welcome!I'm writing because some serious problems with G580 (59-346104) occured.I've decided to change my C (Windows8_OS) pearition size (850 GB is far to big ammount of space for system files only, I need much more space for my files at another partition). I used the AOMEI Partition Assistant Home to resize C to 150 GB and after that I assigned the 250 GB/each of my 3 new partitions which I need for my files. After applying changes, restarting and resizing the space, AOMEI told that it's required to restart for further resizing process. When computer finished the loading process, the blue screen appeared (with " ") that says "system encountered problems with boot-up and will be re-run, check Inaccessible boot device error" (I don't remember the accurate message but such is the sense of) and so he does but after another restart this message apperas one more time and so on. I've tried to start a recovery but when I run computer with NOVO button and afterch choosing recovery, the system says "Lenovo recovery system boot failed" and then computer starts the "normal" boot proces (which lead to the problem described above).As soon as I know (at least I guess so) where is problem, I have no idea how can I repair this.I'll be very grateful If someone will help me.Gaclav

Preferred Solution: Inaccessible boot device and Recovery system boot failed after resizing partition

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Inaccessible boot device and Recovery system boot failed after resizing partition

Hi Gaclav,

Thanks for posting and welcome back to the Lenovo Community,

I?d like to confirm to you that the recovery won?t be working more as you?ve performed resized for the partition and changed the Hard disk size which cause the recovery to be corrupted,

And the only way to get the recovery the system back will be contacting contact support and am afraid to tell you that it would be billable repair at the service center:

Okay, so this just happened out of nowhere. Nothing seems to have led up to this -- the system booted and shut down successfully, and no software updates or installs were done during the period of time it was on when it was last working. I've attempted many things, but none seem to work. /ScanOs reports no OS detected, while startup repair said the OS was booted successfully. bcdedit also shows no directories linked to "unknown". CHKDSK reports no bad sectors, so such can be discarded. This happens every time I attempt to boot to Windows 7 (Home Edition, x64). I have a copy of Fedora 17 set to dualboot with it, but it hadn't been booted for over a week before the event. Any suggestions?

I bought a new laptop and in order to move my data to it, I took out the hard drive of my old laptop and hooked it up to a SATA device. After that, I put it back in the old laptop. When I turned it on, it would not boot because of the device (hard drive) being inaccessible with an error code 0xc000000e.

I do not have the Windows installation CD to run the repair, I ran a BIOS diagnostic and it found nothing, the boot order in BIOS is correct. Any further ideas?

Answer:Boot selection failed because of inaccessible device

What OS is on each machine?

If they're both Win7 64-bit then create a system repair disc on the working machine and boot the other using that disc and select repair from the menu.

If they're different, you could try downloading the ISO here. Be sure to select the correct bitwise ISO (32-bit or 64-bit) and then create a system repair boot disc.

Then follow this tutorial: Startup Repair

- Re installed my ram
- Booted with on board graphics
- unplugged all usb devices and external devices with the exception of the keyboard and mouse
- Booted with system installation disc and attempted system repair several times only with the same outcome of wanting to restore from a previous system restoration point however it always fails
- changed the boot type to IDE which made the system boot furhter past the logo screen however it still crashes with the same error

re installed windows 7 from hidden partition. Now when I go to boot up computer I get black screen that says:

Status: 0xsc000000f
Info The boot selection faile because a required device is inaccessible.

Any help would be appreciated!

Answer:''Boot selection failed because a required device is inaccessible''

Old hard drives are mechanical devices with spinning platters and reciprocating heads. These moving parts cause wear. And, when this wear becomes great enough, it is no longer possible for the heads to zero in on exact locations where data is stored on the hard drive. In other words, it's simply worn out.

I have an Intel i5, Windows 7 Ultimate, and an SSD as my main drive and 2 SATA HDDs.

One day, I got a BSOD appeared and my PC restarted restarted. After that, the following error appeared:


Window failed to start. A recent hardware or software change might be the cause. To fix the problem:
1.Insert ....
2. .... ... status: 0xc000000e info: The boot selection failed because a required device is inaccessible


Also I noticed that BIOS only detected one of HDDs, not SSD neither other HDD.

Sometimes, Windows can be started, but it doesn't work very well.
When trying to copy data from F: to an external USB, it copies for a short time and then Win7 becomes unresponsive. This also happens in safe mode.

After several reboots, now Windows will not boot and I get the error "The boot selection failed because a required device is inaccessible." And the BIOS only detects the SSD.

UPDATE: my disks:

HDDs
WDC WD10EARS-22Y5B1
Seagate ST31000528AS

SSD
FM-25S2S-120GBP2 - G.SKILL



Any suggestions?

Answer:the boot selection failed because a required device is inaccessible

Hmm, that looks rather choppy. Sounds like your disks have a physical connection problem. I suggest you check that.

Also, if the SSD seems to connect but the OS cannot be loaded, that would suggest that your bootmgr does not reside on the SSD.

Download an burn the bootable CD of Partition Wizard (last entry on the webpage). With that you can inspect your disks without the OS. Just load the CD.

Recently I shrank one of the partition on the data drive in order to enlarge the other partition on the data drive. The enlarged data drive contains the folders of some installed games but the system disk is separate and was not altered in this way. I'm pretty sure that I hibernated and recovered from hibernation at least once since that change was made.

Could it be that the OCZ drive has developed a fault? Or would it then be unable to even display this message?

When I attempt to repair the installation using the Windows 7 disc, the operating system isn't listed. I don't think that there are any drivers for me to load - I think it's supposed to be automatic (the driver must be a part of Windows own included set).

Hello,
Installed Acronis True Image Home 2011 a couple days ago. I did not setup any items within Acronis yet for backups, etc. After install my system appeared O.K. and have shutdown/restarted several times without issue. Yesterday, the computer shut down inadvertently, then at boot i get this message:

Title Screen: Windows Boot Manager
Status: 0xc000000e
Info: The boot selection failed because a required device is inaccessible.

Problem? I suspect something with Acronis damaged by Windows 7 boot files.
How to fix????

In reading the various postings on the web (including Windows 7 forum!), it seams that Windows Startup Repair would be the best bet to resolving my issue. I put the DVD in, reboot, I see a scroll bar the bottom and text says "loading files....", then I see the "Starting Windows" splash screen with the Windows 7 logo...and that's it. The system never gets to a point where I can choose my language, select repair options, etc.

So....I read on the forums the Easy BCD would be a good tool to fix my issues. I downloaded it on a separate system and check it out. It looks like a GUI based program, so I'm confused on how to run it on my Windows 7 system that won't boot. Can I make a bootable version of Easy BCD?

Is correcting the BCD my issue? I don't know

I loaded Partition Commander 11 to check things out...I see a "System Reserved" partition which has bootmgr and the BCD files on it, I also see my partition where Windows 7 is ... Read more

Answer:oxc000000e Boot failed-required device is inaccessible

Please post back a screenshot of your maximized full Disk Management drive map with listings, using Snipping Tool in Start Menu.

Not sure how Win7 booted if you deleted SysReserved partition then only marked Win7 partition Active but didn't run Repair a few times to write the System boot files to 7 partition with only it's HD plugged in.

Possible that Win7 may be booting off the XP partition which is why we need to see the screenshot and know what you want to do.

Hi there

Hoping someone can help me with this booting problem.

About six months ago my hard drive failed and I had buy a new HD and re-install Win 7. I had created a backup on an external HD, but for some reason I could not restore the computer using this backup. I'm not sure if any of the backup data transferred onto the HD when I tried to do this. I therefore did a clean install of Win 7 and then copied the files I wanted across from the backup on the external HD.

Now, whenever I switch on the laptop the first screen I seen is the from the Windows Boot Manager, which says "Windows failed to start. A recent hardware or software change might be the cause.... and it gives the "status as 0xc0000225. Info: The boot selection failed because a required device is inaccessible."

I then hit enter and the laptop boots successfully and all is good. The only reason why I have decided to fix this now is because I want to upgrade to Win 10, and I donit want this to cause any problems during installation.

The C drive is where I installed the new copy of Win 7 Op System and the E drive is the partition I created to store my data files etc. I'm not sure what the other drives are?

I have attached screens of the screen descibed above and also the Windows disk management screen.

Thanks for your help.

Hi all,

I'm desperately in need of help.

I just talked my gf into restoring her dell inspiron 5010n. It was getting slow and running way too many background programs (she likes to download games). We also believed that it was infected due to some program glitches.

Anyway, after copying all of her personal files to discs, I tried to reset her computer to factory settings through the control panel recovery advanced options.

The option to recover from disc was available (I created the discs right after we took it out of the box about 18 months ago), but would not initialize upon clicking on that option.

So, I inserted the recovery disc 1 into the cd/dvd drive and initiated the recovery after restarting the computer. Everything seemed to go well.

Windows started up, and I began configuring her computer. Anyway, windows indicated it needed to restart after downloading 1 update.

When the computer restarted this time, the windows boot manager came up and said:

Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

1. Insert your Windows installation disc and restart your computer.

Answer:Boot selection failed because a required device is inaccessible

When you boot, there should be an F key for you to use to open the boot device menu. If you know what it is (F8 or something during the splash screen), could you use it to see what your boot options are?

I don't think I have seen that type of message before, so not sure what it might be.

You can turn off automatic updates....

Hi, I know a lot of people have posted this but I think mine is different to theirs.

I took a SSD drive used to boot my sons pc, placed it in my computer and cloned it with Norton ghost onto a bigger drive.

When I put the new drive in his PC I got the error "boot selection failed because a required device is inaccessible"

I put his old drive back in, and got the same error as I assume because I placed it in another PC with a boot drive, it removed the boot capability?

I have tried to do a startup repair etc, but none of that will work.

Can I get his old drive to work again? All the info is on there, and I have a fresh install of windows 7 on a separate drive so I can boot in and look at his SSD, but am unsure how to continue.

Google has NOT been my friend!

Answer:boot selection failed because a required device is inaccessible

With both the original boot drive and the new drive with a fresh copy of windows in it, I went into the installation cd and was going to see if both versions came up, but before it gave me any selectable options it said it had fixed an error and would I like to reboot.

After I did it went into a dual boot screen with windows 7, and windows 7 ultimate 64 bit (recovery) options.

When I select the recovery version it boots into the drive like a dream, with everything there, so I closed the system, removed the new drive with the fresh version on it and I now get the missing ntldlr message, so I guess I can fix this with normal bootrec etc. commands.

I'll post on how I get on!

I am receiving this error, when I try and boot Windows 7.

I have run the Repair Startup option from the Installation DVD, and it performed a System Restore [only] the first time, but fails to resolve the error.

I believe this occurred, when I accidentally powered down the computer, while it was attempting to transition to/from Sleep/Standby Mode.

Reading other articles around the web (http://social.answers.microsoft.com/Forums/en-US/GettingReadyforWindows7/thread/5da88257-837d-4475-ad6e-9ea8968826f4)
I get the impression that the accepted solution is a clean install.

Is a Clean Install the only way to resolve this error?

I can provide detailed specs and error reports to assist in any bug-hunting.

Thanks.

Go into your Bios and check to make sure that the right boot drive is selected. I've no idea why, but I've seen the boot drives get mixed in the bios setting on some systems resulting in the computer trying to boot from a non-bootable drive resulting in the error message you have received.

"I did something with the partitions on my laptop" is a little vague.

Hi everybody,

I am dualbooting Windows 7 Ultimate and Arch Linux (using rEFInd boot manager) on a GPT disk and (unfortuunately) have an UEFI system.

My setup used to work perfectly fine, until I recently updated rEFInd - and following this - deleted a paramount file on my ESP: bootx64.efi.

Obviously, I could not boot any OS anymore, so I tried to restore the bootloader but during this process I killed all my partitions.

Luckily, I could restore them using the tool Testdisk on an Archiso live usb stick. I restored bootx64.efi and wanted to boot Archlinux ... where I was greeted by an error message telling me that the root device rEFInd is looking for is not present. I could fix this by adjusting the PARTUUID in the respective config file and now I am booted to Archlinux. So as it seems, recovering the partitions using Testdisk resulted in changed UUIDs for my partitions.

However, I still can not boot Windows 7 because all I see is this boot error:


Code:
Windows failed to start. A recent hardware or software change might be the
cause. To fix the problem:

1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next".
3. Click "Repair your computer".

If you do not have this disc, contact your system administrator or computer
manufacturer for assistance.

You are right that you have changed GUIDs for all your partitions. In this case, it is impossible to recover your Windows with the recovery tool.
You need to manually restore the BCD store with bcdedit.exe. The method 2 in this page will let you know how to do this.

Hi Everyone,

I recently powered my machine down before hitting the power on my main fuse box to carry out some electrical work. I think I may have hit the power whilst an update was in progress. As a result when I try to boot now I am getting BSOD with "inaccessible boot device".

I have read numerous tutorials and the only thing I could get to work was to copy the contents of RegBack to Config - then I was able to reboot. All has been fine for a week however I then rebooted my machine and the problem re-occurred and now the previous fix doesn't work (presumably because the regback files have been updated with newer dirty files).

So I've now tried all option in the recovery console and none work, chk disk reported no errors and I just have the MBR fix left to try.

Is it possible to -reinstall on a new hard drive and then copy something over to the old broken install to fix this boot issue?

If this fails I think I will need to re-install. My question is how can I re-install and not delete/over-write my previous data. I saw some people report that there old install was copied to Windows.OLD. If I could then copy the required file and folders acorss then I can live with this.

Any other suggestions or ideas are welcome.

Thanks in advance,

Bob.

Answer:Inaccessible Boot Device Recovery Options

Hi Bob. Welcome to the TenForums @spacebiscuit75

I don't know of a way to create a second system and then copy the good stuff. (Not even sure what you would copy.) Another member may have a better approach.

We can create a boot disk and use that to copy off your personal data to an external target. Then perform a clean install.

You can create Kyhi's recovery disk at this link.

Windows 10 Recovery Tools - Bootable Rescue Disk

use it to copy data.

Then follow the clean install tutorial here. Since you had 10 on device it will be activated and you do not need to enter a product key.

Clean Install Windows 10

Your system spec tells us little about your system. If you could take a moment to update.

I've used Disk Director successfully before.  This time I attempted to shrink my C: partition so that I could clone to an SSD.  I had 148 Gb on 299Gb that I was trying to resize to 238Gb.  When the dust settled this bleeper reported Corrupt Master File Table.  My gut feeling tells me that 5 years of programs and tweaks are still there.  Does anyone know how to recover?  So far Acronis Recovery Expert, TestDisk and Seagate File Recovery no help.  DMDE shows daylight but what is the proper procedure to work it's magic?
I'm currently copying the D: partition of the afflicted drive just in case.
Help.

Answer:Partition resizing failed-now corrupt master file table on boot drive

When you ran Testdisk click on Advanced then Boot. Does it show that the backup MFT is intact?  Even the backup is actually only a few first bytes fo the MFT so it may not work even if the backup is listed as okay.
 
Also, if you can create a System Repair Disk on another computer with Windows 7 doing a chkdsk /r will try and repair the MFT.
 
You may have to recover your data with a program like Easeus Data Recovery. This would let you recover 1GB for free. After 1GB you would need to purchase a key.
 
This is why I recommend a complete disk image be done when doing any kind of partition movement. Though rare, things can go bad as you found out.
 
I am not familiar with DMDE but I would assume you need to scan the drive for it to find any recoverable files. Here is the online manual.

Hi,
I booted up my computer today to find that whenever I try to select an option from the booting screen, the whole computer froze, as in, the timer counting down the auto choosing feature froze, I couldn't move anything. I thought at first it was the keyboard, as I use a razer product, I thought the drivers weren't loaded and it froze it. I tried it with the standard keyboard it came with and still froze at the screen (by the way, its option chosen is startup repair, im trying to get to start windows normally). I thought it was the monitor next and switch it around to no avail. I then dug around for a few hours to find my window repair disks. I get a prompt on screen to press a button to continue, which then freezes my PC. If I leave it at that screen for a while, startup repair is launched and I get a Status: 0xc000000e and the info says: The boot selection failed because a required device is inaccessible. Also, choosing any option with my motherboard BIOS also freezes/crashes the computer.
I really need help with this guys, thanks.

Hi guys, sorry i haven't had time to introduce myself! thanks in advanced for having a look

Built this pc, thought everything was running stable but i got another BSOD earlier. After it has rebooted i get a message saying 'the boot selection failed because a required device is inaccessible 0xc000000e'. After rebooting once the pc will boot fine to windows 7 ultimate 64bit

The odd thing is that this didn't happen when it was plugged into the marvel SATA 3 controller, it was just slower... because marvel are terrible > so i have figured out that it must be something to do with the RAID controller on the motherboard? I have the latest JMicron SATA drivers from the official ASUS website.

Another curious thing (not sure if it is related but i am going to post it anyway) is that before i rebooted it earlier HDtune was benching the hard drives and showing that i was getting 2.5gb a second which is impossible.. don't know if this has any relevance however..

I have a question about Windows cloning on the Y470. I tried to clone my system to an SSD using the Windows 7 backup/restore feature, but I'm getting an error that says "The boot selection failed because a required device is inaccessible". The error suggests using the Windows install disc to fix the problem. Does Lenovo provide a physical disc or ISO for Windows? I tried downloading the ISO directly from Windows using my serial number, but I got an error telling me to contact the computer manufacturer instead. Alternatively, if they can't provide a Win7 install disc, do you know if the computer's built-in Lenovo OneKey backup tool will work? It takes several hours to create and then restore a full system image, so I don't want to repeat the process without confirming that this is the proper solution.

Just installed Avira antivirus and rebooted to complete the installation. I am getting the error "Boot selection failed because a required device is inaccessible" whenever I attempt to boot. I have tried using the Windows 7 disc to repair but it does not work as it runs for a few seconds then instructs me to reboot.

The hard drive was initially not appearing but luckily I can now access all my files from this OS, however I would really like to gain access to my main OS again. I have also reset the CMOS but it hasn't changed anything.

Any help would be very much appreciated. Thank you. Sorry if I posted this in the wrong section.

Hello,

Last night i was trying to update my AMD SATA AHCI Controller driver, but i shouldn't do while being sleepy....

My hand moved before my brain realised...I uninstalled the device BUT i also checked the option for deleting the drivers.

Now, i get the error while booting :

The boot selection failed because a required device is inaccessible


What i realise is that windows are trying to find the device needed to boot ( stored on boot info) , but device is not there.

Ι already searched the forum for similar problems and already tried to do a Startup Repair from Windows Installation Disc repair menu (3 consequent times as written), with no result.

No restore points either.

Is there any way to manually fix this or my only path is a repair install ? All my data are safely backed-up.

Thank you in advance for your help.

Well, i found the solution after some 50-60 Google results reading...

Solution was found in this page.

Analytically :

I loaded Recovery Console from my Windows 7 Installation Disk.

Had the AMD SATA Driver folder copied to a cd from my second pc. Driver directory was "W764A"

Ran diskpart and list volume to check the cd's volume letter

Ran the following command ( D: is CD ROM, D:\W764A is Driver Directory, C: is Windows Installation ) :


Code:
D:\dism /Image:C:\ /Add-Driver /Driver:D:\W764A\ /Recurse
I typed exit to exit Recovery Console, rebooted and voila....Windows Started normally...

Glad it was solved....

Soo... things have gone from bad to worse.

My problem started after windows 10 updated when I shut down my laptop for a quick restart. Windows explorer would crash every second, reopen, then crash again without stopping. I tried a system restore to a restore point about a week ago, no dice. I decided to try resetting the computer using Windows built in tools. Everything was going well until it tried to boot after, and now i'm stuck with a BSOD that reads "inaccessible boot device". On top of that, trying to boot into BIOS or to a DVD or to USB are ALL failing. Attempting to access the BIOS (holding F1 as system boots) results in the "Lenovo" logo just hanging until I let go of the button, at which point it tries to boot into windows and fails. USB stick with Windows 10 installer on it isn't working, and the DVD drive boots up and whirrs for a second when the laptop turns on, buit then stops and the computer goes back to trying to boot from windows. (No "Press any key prompt, etc. The little Windows spinning circle of balls comes back on and tries to boot to windows)

Pressing F12 gets me the boot menu, but I have only 3 options :
"Windows Boot Manager", which goes into loading windows and BSOD.
EFI Network 0 for IPv4 (says no media)
EFI Network 0 for IPv6 (again, says no media)

However, the software is unable to restore the PC, reset the PC, or fix the boot issues. It says a partition is missing. Has my hard drive completely failed? At this point, that's the only problem I can think of.

I'm having an issue with a SSD which I put into a different laptop, and now whenever I try to boot I get a INACCESSIBLE BOOT DEVICE BSOD, even in safe mode.

The following is what has happened so far. I just purchased a laptop to replace my main laptop, and I removed the SSD from my old laptop and put it in the new one. I was expecting Windows to install the needed new drivers when booting and then continue to boot to Windows, which is what happened the last two times I put the SSD into a different computer. However, instead of this, I was met with a BAD POOL HEADER BSOD, when I tried to boot Windows. I was also unable to boot into Safe Mode, as I was getting a PAGE FAULT IN NONPAGED AREA BSOD.

I was getting the same BSOD in Safe Mode on the previous laptop, but it was always booting fine when booting normally.

I've taken a number of steps to try and resolve the BSOD, without any success. I did a system backup with Todo Backup, and then restored it to the SSD using the System Transfer restore, which is designed to do a restore to dissimilar hardware. This made no difference. I also tried doing an In-Place Upgrade on the original laptop, and I planned to put the SSD in the new laptop again after the first reboot. But, the In-Place Upgrade always fails a few seconds after Windows Setup informs me it will reboot shortly. I tried the following to get the upgrade to work. I did a clean boot. I did a clean uninstall of my antivirus (I ran the uninstaller, followed by ... Read more

This bug check indicates that the Microsoft Windows operating system has lost access to the system partition during startup.

I'm in a really awkward situation.
Basically my base 1tb hard driven will not boot windows off of the main partition.

I've been messing with a live Ubuntu usb for a bit. Today, I accidentally began installing Unbuntu to my caching mSATA. I exited out of the installation and reformatted the cache drive. I think this is when my C:/ drive was no longer recognized by Ubuntu. Gparted said something along the lines that it was unstable and missing magic, so run chkdsk /f on it.

I restarted my computer, but was prompted to insert a bootable drive. After doing some serching, I created a recovery disk on my USB and booted that. My C: drive with the is was nowhere to be found.

Using command prompt, I opened DISKPART and reactivated the drive. It is now visible, when searching for drivers at the beginning of the recovery disk, but is not accessible or recognized as my OS drive.

Attempting to run CHKDSK will report it's NTFS, but not not find a volume or state. The partition was even hidden at one point, so I fixed that in DISKPART. Also DISKPART reports the partition is raw.

I've tried the start up repair to no avail and rebooting just gives me a unresponsive black screen with blinking terminal cursor. I'm really out of ideas what to do. Can I fix this problem or at least recover my 700+ gigs of files?

Thank you for your time and advice.

Went out and bought a new ethernet card. Installed in an open PCI slot. Tried to install the drivers off the floppy provided. Got error message that inf file did not match the one specified. Took the card out; took out the old ethernet card; put the new one in that slot; tried again. Same error message.

In the meantime, my 5-year-old turned off the power source while the computer was on. When I tried to power up again, I got the following error message: ***STOP: 0x0000007B (0xF081B84C, 0xC0000034, 0x00000000, 0x00000000) INACCESSIBLE_BOOT_DEVICE.

My MOBO went out and I had to replace it.. After I finished, the Windows2000 splash screen came up for about 2 seconds then I got the "Blue Screen Error" "Inaccessible_Boot_Device".. I tried booting with the w2k installation cd <no luck, same thing happened>.. Was going to try to boot using the MSDOS boot disk <but lost the darn disk>

Anyone know what the heck I can do short of Deleting my Hard drive??

Please keep in mind I have limited funds..

I'm on windows 2000 professional and got a Blue screen with Stop Inaccessible boot device message this morning. As previous postings it says to Chkdsk/F, but how do I do this as I can't get a dos prompt.I've options to press DEL on startup and F8 during windows front screen but then when I get blue screen everything stops.I though it might have been due to removing some software, but I've tried booting from Set up disks but get through to disk 4 when it gives a message of disk.sys is corrupted.Any thoughts?Thanks

Answer:Inaccessible boot device

download a new win2k floppy set from click hereOr just boot from a win98se boot disk and run chkdsk/f

My recent Windows installation has gone awol after I changed a heatsink and fan. When I try to boot the computer it gets as far as the white "Windows 2000" splash screen then immediately goes to a blue stop screen with "Inaccessible boot device" on it. It does it every time. I tried to run a Windows repair from the CD, but afterwards I booted to the same blue stop screen. Then I tried the CD in recovery console mode, but when it asked me for my password and I entered it, it told me my password was invalid!It appears that the fault is in the bootable part of the primary master hdd. If I try to load the Windows Recovery Console it tells me my administrator password is invalid. I know 100% that it is valid, and caps lock is off. I assume my administrator password is stored in the boot sector of the drive? If so, then it appears the Windows CD also cannot access the boot sector.I did put a fair bit of pressure on the board when changing the fan and heatsink, but I have no reason to suspect at this stage that any damage has occurred as a result of this pressure.This is a fairly recent installation, less than a month old, and has been running flawlessly up 'til now, with no errors or problems. Something has destroyed my boot sector, I cannot think of any other explanation for the repeated boot failure. It seems the Windows CD is unable to access the boot sector to repair it. Is there a miracle freeware boot sector repair program I can download and image onto a floppy?

Answer:Inaccessible boot device

mmm... first I'd be inclined to see if you can recover data - then set about resolving boot issues? To this end do you have a "linux on a cd" variant (Knoppix/Ubuntu etc.)? If so boot up with it and transfer data off to optical media; verify those copies are truly accessible on the same system (via linux) and another system too. Then set about phyxing problems various?

Dell also has a great feature in that you can restore it to its bought condition. Again, you have to get dell support to do this. if you have data you want to save, you lose that however. dell should be able to help you access your bios and make sure the boot device is turned on...doc

I am working on getting our Windows 8 image working for an upcoming deployment. I am running into an issue when deploying to the Dell Optiplex 745. I am deploying via PXE and MDT/WDS. This method deploys fine to our DakTech models and even our Lenovo T60 laptops. I can install from the DVD just fine on the machine. I have extracted the drivers from the ?reference machine? and added them to my deployment share. I have still receiving the ?error inaccessible boot device.? This image is from the DVD not a custom image, but I have tried a custom image from my reference machine with no luck. I have also tried both the normal and the legacy settings for SATA operation in the BIOS. I have since run across this issue with a Lenovo desktop as well.

This morning I tried to wake the computer from sleep and it crashed twice. On the third reboot the bios recovery came up and switched to bios B. After that my CPU temps were crazy high. I downloaded the current bios and replaced both bios with current Bios. High temps went away.

On to sys boot; it won't. I keep getting a bsod with "inaccessible boot device". Check disk is clear. System won't repair. System restore results in the same crash. I am currently attempting to mount my system image, without much faith. Next will be a clean install, which I really don't want to do.

Please tell me you have some advice for me.

I ran into a problem this evening with my laptop, Lenovo B575. The laptop kept restarting because of inaccessible boot_device. I am not sure how to fix this problem. I know it's too new for everyone with Windows 10. Mine is Windows 10 64X Home Premium operating system. Before that I had Windows 7 64X Home Premium and never went into WIndows 8 till free upgrade of Windows 10 two weeks ago. I don't think that I gave you enough information about this happened earlier today. I clicked the button " resetting the laptop. " After reset the laptop and got into this problem after restart the laptop. Here is the message I got from my laptop and look below:

Your PC (my laptop) ran into a problem and needs to restart. You can restart.

If you'd like to know more, you can search online later for this error: INACCESSIBLE BOOT_DEVICE.

I did try to restart the laptop but can't so I turn off the laptop and turn on again then ran into the same problem as above.
Any idea how to fix this problem otherwise I might have to take to computer repair place to get this fix.

Thank you,

I'm trying to install windows 2k on this pc and it's giving an inaccessible boot device error(code 0x0000007B)

the real problem is that there shouldn't be a problem.
I resized my main partition to make 2gb of unallocated space.
I partitioned and formatted the space as NTFS
I can access it from vista and move files freely into and out of it,
but when I try to install win 2k it gives a bluescreen error after loading its components.

I'm trying to put 2k on so I can play metal fatigue, system shock, and other old games.

I'm confused as to how there is any error at all.

The automatic fix program said it was the error designated as Inaccessible Boot Device. I tried the system restore from two recent restore points offered by my PC. Didn't help. I tried startup repair - didn't help. System image recovery didn't work because windows couldn't find a system image on my computer.

Sir, I had upgraded my Acer Aspire Laptop (CORE i5 - 4GB RAM) from Windows 8.1 to Windows 10 recently. As it was running very slow, I decided to do a 'clean reset'. By mistake, the recovery partition also cleaned. It then went to a blue screen saying "Your PC ran into a problem and needs to restart. We'll restart for you" and appeared the error code INACCESSIBLE_BOOT_DEVICE, and it is keep on restarting again and again with the same error.
I dont have windows 10 System Recovery Disk, but I have Windows 8.1 System Recovery in USB. However, the system is not booting from the USB. When I tried to change BIOS Boot order, the system asks a password, but I didnt give any password.

Hello Everybody, Just bought a Lenovo G580 notebook with pre installed Windows 8 (500gb harddisk, 4 gb RAM, Intel B960).I have been using Easeus partition manager with Windows 7 & its been working very well.So I wanted to partition my new HDD with it.Upon creating the a new 100gb partition (most importantly from OS partition that was about 428 gb) a very strange thing happened.The Refresh/Reset functions of WIndows 8 stopped working saying required recovery files are missing, also Lenovo One Key recovery program does not work with the message that required service partition is currently unavailable.At the same time, apparently  partition called Windows recovery  (1000 mb, hidden) still exists.One more peculiar thing I noticed & that is there is a new 1mb unallocated partition before the Windows recovery partition.While partitioning I did not receive any message about deleting of any data.One last piece of information (not sure if relevant) is before doing partition I had created a system image that I am unable to restore, Windows 8 repair function recognises the image bit is unable to restore it. Any ideas how to restore the System Recovery functions or how to restore the system image. ThanksPetr

I installed windows seven beta a few weeks ago. I made the partition too small at the time and just recently used a live ubuntu cd's partition editor to add more space to the windows seven partition.

When I booted into vista it automatically check the drive and restarted with no problems.

When I attempted to boot into seven it gave me an error screen saying I need to reinstall my O.S.

I have lost my cd for the beta build. Is their anyway I could get a copy of the iso from Microsoft again? Or would it be easier to upgrade to the release candidate? Or can I posiblely repair without the cd (when I try to acess the extra features of f8 on the boot screen I get the same error as trying to load the os)?

Answer:Seven boot problems after partition resizing

What error do you get?

In Vista , rt click the 7 partition and run check disk.

Also, have a look in Disk Management and see if the 7 partition shows up correctly.

If it does, may be able to fix it using bcdedit in Vista.

If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:

Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated, run CHKDSK/F to check for hard drive corruption, and then restart your computer.
How can l check my computer for a viruse if l can't get into it??

What did l do this time and how can l fix it?

More than likely it's not a virus. Most often than not, this is caused by a bad hard drive. I would replace the drive.

I'm running Windows 10 64 bit without any problem. Dual core cpu 3 gb ram gigabyte motherboard. 320 gb sata hdd. Everything's okay until i connect an additional 160 gb sata hdd from another computer.

What happened:
1. When i connected 160 gb sata hdd, it booted XP os. I know that bios recognized it as the first boot device.
2. I changed the boot order where my windows 10 installation is present.
3. BSOD with a message inaccessible boot device.
4. When i remove that 160 gb hdd, windows 10 boots like nothing has happened before.

What i did:
1. Booted live ubuntu and deleted partitions on 160 gb hdd from disk utility menu. It has some extended partitions which I'm going to delete as my pwfree_64.iso gets in my bootable usb flash drive.


What i want:
I want that 160 gb hdd fully formatted connected to my computer without any boot errors.

Please help me. I've encountered this issue for the first time in my life.

Answer:Inaccessible boot device error

Still seems like bios is the problem. Do you have a BIOS that supports both Legacy and UEFI booting? You might have changed the boot priority for Legacy but not for UEFI. Is there an option to enter the manual boot menu screen? On my laptop it is F9, on my desktop it is F11. Try entering the manual boot menu and see what the options are for booting, that will help tell you what to set as the priority device. Also, make sure the SSD is connected to the first SATA port on the motherboard, then I like to do CD/DVD drives next, then storage hard drives.

Also, post a complete disk management screenshot and that will help us:

I'm in a quandry here and can't figure out how to get out. I was reinstalling my HP scanner software when a stop error screen came up during reboot. I tried restarting and I keep coming back to the same screen. I tried booting from my Norton Antivirus Emergency Boot Disk and keep getting stuck at the same screen. I tried going into safe mode with command prompt and still come to the same screen. I checked the connections on the back of the computer and have unplugged the scanner. Still no luck.

Here's what the screen says:
_______________________________________________________

***STOP: 0x0000007b (0xEB81B84C, 0xCOOOOOOE, 0x00000000, 0x00000000)
INACCESSIBLE_BOOT_DEVICE

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

Refer to your Getting Started manual for more information on troubleshooting errors.

I was working on my computer, Windows 2000 Pro. - I was moving my foot under the desk and accidentally switched off the surge protector.

I turned the protector back on and restarted my computer. I get a royal blue screen that says Stop Error.... "Inaccessible Boot Device"

None of the F8 options work for restart, they all say the same thing. I really don't want to have to reformat... Can someone please help ASAP?

Thanks!

Answer:Why does my screen keep on saying inaccessible boot device?

Hah! I suppose you may have screwed up Windows. I suggest you reinstall Windows from the beginning. If it's already in that state, there is no hope to recover what you had on your computer, at least that was what happened for me.

Hello! I've just tried turning on my PC and it shows me a BSOD saying INACCESSIBLE BOOT DEVICE. Yesterday everything was fine. I turned it off normally like always. I haven't updated any drivers either and there are no external drives or USBs connected. I liked for some solutions but none worked. I tried booting into safe mode (got the same error), I checked if my SATA options werr on AHCI (which they were). What do I do? I don't want to lose all my data!

I just replaced my P11 450 with a gigabyte mb and a P4 1.8. While initially all looked well, during the boot into Windows 2000 that wonderful blue screen with tons of words, among them, inaccessible boot device.....check your hard drive...blah, blah, blah came up. The only difference between the new configuration and the old is the MB and processor. What stupid thing did I miss? I'm guessing that there may be something in the BIOS that I've misset. Help!!

Answer:[Solved] Inaccessible boot device

You will have to reinstall Windows. It does not like you changing the hardware, which includes BIOS and CPU. The reason is Windows create a Hardware Application Layer (HAL) to separate the OS from the hardware when installed.

hi I have been trying to install XP 64 bit on a partition on my laptop and half way through i get a blue screen: 0x0000007B inaccessible boot device and this is quite frustrating because i can install XP 32 bit successfully but not 64bit.

Answer:XP 64 bit 0x0000007B inaccessible boot device

When you power on your computer, look for a message telling you which key to press to enter your BIOS Setup - usually Delete or F2. Go into setup and change the hard drive setup from SATA to something like Compatible Mode or IDE Mode. The description varies. After you get Windows installed you'll have to update all your chipset drivers then change the hard drive access mode back to SATA.

I had Win10 working until I did a clean install, now it continually reboots with the BSOD error message "INACCESSIBLE_BOOT_DEVICE." So far I've tried:Resetting BIOS to factory defaultsCreated USB repair disk (via MS's media creation tool) --startup repair - "unable to repair. log file ... .txt" --Reset PC - "There was an issue resetting this PC." --Command prompt - diskpart -> list volume -> chkdsk /f /v /r c: - ".....no further action required"Under diskpart, c is about half the size it should be, but there is no raw volume, it seems to simply be missing. Any ideas?

Answer:Inaccessible boot device ASPIRE ONE

if you don't mind to backup data, do a clean command on diskpart to wipe completly your HDD and start again with windows 10 installation.
